I personally like the interface. It seems like some users complained about the gold color, but I think it gives it some snazz! Besides, since iron is supposed to be a valuable resource in this game, the gold interface makes the player character seem somehow special or otherwise not restricted by the mundane laws of the average citizen of the world. Maybe I’m looking into it too much, but the gold seems like a good representation of the player character (and it doesn’t seem gaudy either, in my opinion).
